Recessed Chin
Also: retrogenia, weak chin, chin retrusion
A recessed chin (retrogenia) is a chin that sits set back relative to the rest of the face when viewed from the side, rather than projecting forward to roughly the lower lip or E-line.
What is a recessed chin?
When viewed from the front, most people's chins look broadly similar. The side profile tells a different story. Chin projection — how far the chin point extends forward relative to the lips and nose — varies considerably from person to person, and that variation shapes the entire perceived character of the lower face.
A forward-projecting chin creates a clear, defined transition between the lower lip and the neck. A recessed chin, by contrast, sits behind the lower lip line, blending more softly into the neck and often making the neck appear shorter or the lower face less defined in profile photos.
The clinical term is retrogenia — literally “backward chin.” It refers strictly to the position of the chin point (the menton), not to the jaw bone as a whole. It is a common, natural variation in human facial anatomy, not a medical condition.
How to tell if your chin is recessed
The most practical check is a side-profile photo. Stand in neutral lighting, let your teeth rest lightly together, relax your lips, and take the photo at eye level — not from below.
Facial clinicians use a reference called the E-line (esthetic line): an imaginary line drawn from the tip of the nose to the tip of the chin. In a well-projected profile, the lower lip touches this line or sits slightly behind it, and the upper lip sits 2–4 mm behind it. The chin itself, by definition, sits on the line.
If your chin falls noticeably behind the lower lip in a relaxed side-profile view — especially if there is a visible soft-tissue “step-back” rather than a smooth transition — it is generally considered to be recessed relative to the average.
A simpler approximation: look at a relaxed side-profile image and trace a vertical line down from your lower lip. If your chin falls behind that line, you likely have below-average projection. If it meets or passes it, your projection is average to above average.
Note: these are aesthetic reference points, not clinical diagnostic criteria. Self-assessment with photos is imperfect and should not replace a professional evaluation if you have concerns about bite function or jaw development.
Quick profile self-check
- 1.Take a side-profile photo at eye level, natural lighting, face relaxed.
- 2.Find the most prominent point of your lower lip.
- 3.Draw or visualize a vertical line straight down from that point.
- 4.See where your chin point lands relative to that line.
- 5.Behind the line = recessed. At or forward of it = average to projected.
Recessed chin vs recessed jaw vs overbite
These three terms overlap in casual usage but describe distinct things. Getting them right matters — especially if you are thinking about options.
Recessed chin (retrogenia)
The chin point specifically sits behind the lower lip and nose in profile. The jaw itself may be in a normal position — only the chin's forward extent is reduced. This is purely a structural/aesthetic variation of the chin bone (the mentum).
Recessed jaw (retrognathia)
The entire lower jaw (mandible) sits further back than the upper jaw. This affects the whole lower-face profile, not just the chin tip. It can cause bite issues and airway effects because it involves the position of the jaw joint and the teeth, not just the chin point.
Overbite / overjet
An overbite describes how much the upper teeth vertically overlap the lower teeth; overjet describes how much the upper front teeth project forward of the lower teeth horizontally. Both are dental/skeletal relationships and may or may not affect chin projection visually. These are dental diagnoses — if you have bite concerns, an orthodontist or dentist is the right person to consult.
If you think you may have a functional bite issue — difficulty chewing, jaw pain, sleep breathing concerns — that is separate from aesthetic chin projection and worth discussing with a dentist, orthodontist, or oral and maxillofacial surgeon.
What causes a recessed chin?
Chin projection is primarily determined by the shape and forward extent of the mentum — the bony chin prominence at the base of the mandible. How prominent that structure is varies between individuals, and the main drivers are:
Genetics and inherited bone structure
The size and forward projection of the chin bone is largely inherited. If your close relatives have similar profiles, that is the most likely explanation. This is the most common cause and applies across all populations — chin retrusion exists at varying rates in every ethnic group.
Jaw development during growth
The lower jaw continues developing through late adolescence. Factors such as extended mouth breathing, thumb sucking in early childhood, or habitual forward head posture during development can affect how the lower face grows. In adults, the structural result is fixed.
Bite and dental relationships
A significant skeletal overbite or retrognathic jaw can position the lower face further back than it would otherwise sit, making the chin appear more recessed than the chin bone itself would suggest. Here the chin is not the primary issue — the bite relationship is.
Soft-tissue factors
Body composition affects the chin and neck junction. Higher levels of submental (under-chin) fat can visually soften the chin's apparent projection regardless of the underlying bone. Lower body fat and a stronger neck typically make the chin look more defined.
Can a recessed chin be improved?
It depends on what you mean by “improved” — and being honest about the options saves a lot of wasted effort.
What can change the look (without surgery)
- Posture: Neutral head posture — ears over shoulders, chin slightly tucked, not protruding forward — gives the lower face the best possible presentation. Forward head posture compresses and rounds the neck-chin junction, making the chin appear more recessed than it is.
- Body composition: Reducing submental fat sharpens the chin-to-neck transition and makes existing bone structure more visible. This is real and measurable — but it changes the neck silhouette, not the bone.
- Facial hair: Beard styling can visually extend the chin point and sharpen the lower-face silhouette in profile. One of the most practical and immediate changes available to those who can grow facial hair.
What the evidence does not support
Mewing (sustained tongue-to-palate posture) is widely discussed online as a way to reshape the jaw and chin over time. In adults, there is no peer-reviewed clinical evidence that it meaningfully changes chin projection or jaw bone position. Good tongue posture is a reasonable habit, but the structural claims made in before-and-after content are not clinically validated. Approach those claims with skepticism.
Medical and surgical options (consult a professional)
Chin implant (mentoplasty): A solid silicone implant placed in front of the chin bone to add forward projection. One of the most commonly performed facial procedures globally. Results are predictable for isolated chin retrusion where the jaw and bite are otherwise normal.
Sliding genioplasty: The chin bone itself is cut and repositioned forward (or in other directions) with plates and screws. More invasive than an implant but allows three-dimensional repositioning and leaves no foreign material. Often preferred for larger corrections or when vertical changes are also needed.
Orthodontics and jaw surgery: If the chin retrusion is secondary to a skeletal bite problem, treating the bite (through orthodontics alone or combined with orthognathic surgery) may improve chin position as part of the overall correction.

Recessed chin — frequently asked questions
What is a recessed chin?
A recessed chin (also called retrogenia) is a chin that sits set back relative to the rest of the face when viewed in side profile. Instead of projecting forward to roughly the lower lip line or the aesthetic E-line, the chin falls behind that plane, giving the lower face a softer, more sloped silhouette.
Is a recessed chin the same as a weak jaw?
Not exactly. A recessed chin refers specifically to the forward projection of the chin point itself. A recessed jaw (retrognathia) involves the entire lower jaw sitting back, which can affect bite as well as profile. A person can have a recessed chin with a normally positioned jaw, and vice versa. If you have concerns about your bite or jaw function, see a dentist or orthodontist rather than treating both as the same issue.
Does a recessed chin mean something is wrong?
Not inherently. Chin projection exists on a wide spectrum in the population. A chin that sits back from the E-line is a natural variation of facial structure, not a defect or health problem. It only becomes a functional concern if it is associated with airway or bite issues, which a specialist can assess.
Can mewing fix a recessed chin?
There is currently no peer-reviewed clinical evidence that mewing (tongue-to-palate posture exercises) meaningfully changes chin projection in adults. The technique may support good tongue posture habits, but claims that it visibly reshapes adult bone structure are not supported by published research. Be skeptical of before-and-after claims online.
How can I check if my chin is recessed?
Take a neutral side-profile photo in natural light with your teeth lightly together and your face relaxed. Draw or visualize a line from the tip of your nose to the most prominent point of your lower lip — this is a simplified version of the E-line. If your chin falls noticeably behind that line, it is considered to have lower-than-average projection. Tools like the Symmetry IQ Face Proportions Test can give you a more structured baseline reading.
